MPROVEMENT IN MACHINES FOR MEASURING GRAIN.

Specification forming part of Letters Patent No. 39,959, dated September15, 1863.

To all whom it may concern:

Be itknown that I, CHARLES Boss, Hartland, in the county of Livingstonand State of Michigan, have invented a new and improved device fortallying or registering the measures of grain as the latter is drawnfrom a bin or grain-receptacle 5 and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, making a part of thisspecificatiomin which- Figure l is a front view of my invention; Fig. 2,a section of the same, taken in the line 00 00 of Fig. 3; and Fig. 3, aside view of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in connecting in a novel way the slide whichcovers the disehargeopening of a bin or gram-receptacle with aratchet-wh eel,havin g an index attached to it which works over a dial,all the parts being arranged in such a manner that by operating theslide so as to open and close the discharge-aperture, the ratchet-wheelwill be turned and the number of measures drawn from the bll indicatedby the index on the dial.

To enable those skilled in the art to fully understand and construct myinvention,[ will proceed to describe it.

A represents a portion of one sideof a grain bin or receptacle, and B isa slide which is fitted between guides a a, attached to the inner sideof the bin A.

G is a discharge-opening made in A, and at such a. position relativelywith the slide that the latter may be moved or adjusted so as to coverthe former.

D is a metal arm, which is attached vertically to the back part of theslide B. This arm extends upward to the upper surface of the upperguide, a, and has a block, E, at tached to it, the under surface of saidblock being on the upper surface of the guide a, on which the block isallowed to move freely as the slide B is moved. The upper surface of theblock E is of inclined form, and slightly rounded or curved, as shown inFig. 2.

F is a box, which is attached to the inner side of A, just above theguide a and block 1 E. Within this box F there is placed aratchet-wheel, G, the front journal, I), of which passes through A andhas an index, H, attached to its end. This index works over a circulardial, I, on the front side of A. (See Figs. 1 and 3.)

J is apawl, which is formed of a fiat piece of steel bent inright-angular form. One end of this pawl is secured to the outer side ofthe box F, as shown at c c, and the opposite end passes through a slotor opening, (I, in the bottom of box F, as shown clearly in Fig. 2. Thispawl J is, when not acted upon, kept free from the ratchet wheel G byits own elasticity, and the pawl is directly over the block E and insuch a relative position with it that each time the slide B is moved soas to close the discharge-openingG of the bin or grainreceptacle, theblock E forces upward the pawl J, and the latter thereby turns theratchet-wheel G the distance of one tooth, and the index H will beturned the distance of one graduation on the dial I; hence each measureof grain drawn from the bin will be indicated by the index on the dialas the slide B is shoved inward, and the dischargeopening 0 closed eachtime the measure is filled.

I would remark that the ratchet-wheel Gr may be provided with aholding-pawl, or afriction-plate, K, may be made to bear againstitsjournal b, in order to preventthe ratchet from turning during thedescent of the pawl.

I am aware that tallying-machines already exist in which ratchet-wheelsand indices are employed, and I do not claim the invention of suchdevices; but,

Having thus described my invention, what Patent, is-

The combination, with the frame A, discharge-opening U, and grain valveor slide B of a grain-bin, of the arm D, inclined block E,actuating-pawl J, and index-box F, containing the indicating mechanism,in the manner and for the purpose herein shown and described.
